Split-level high-speed rail platform door with underneath drive

Abstract

The invention relates to the field of high-speed railway / intercity railway platform screen doors, and particularly relates to a split-level high-speed rail platform door with underneath drive. The platform door comprises a plurality of movable door unit sets which are continuously arranged in the platform direction, and each movable door unit set comprises a first movable door, a second movable door, a third movable door and a fourth movable door which are sequentially arranged in a closed state; the first movable door and the third movable door are arranged in a first row, and the second movable door and the fourth movable door are arranged in a second row; driving devices of the first movable door and the third movable door are arranged at the bottom of the first row and staggered up and down, and driving devices of the second movable door and the fourth movable door are arranged at the bottom of the second row and staggered up and down; the first movable door and the fourth movabledoor are configured to be capable of moving to the central position of the movable door unit sets by one or two movable door widths under the driving of the driving mechanisms; the second movable door and the third movable door are configured to be driven by the driving devices to move leftwards or rightwards by one movable door width.

Description

technical field [0001] The invention belongs to the field of high-speed railway / intercity railway platform screen doors, and in particular relates to a bottom-driven split-level high-speed railway platform door. Background technique [0002] The platform screen door system is set on the edge of the platform to isolate the passenger waiting area from the train operation area, and corresponds to the train door. It can control the opening and closing of sliding doors in multiple levels. Generally, there are full-height, half-height, airtight and Non-airtight, referred to as screen door or platform door. When the train arrives and departs, the screen door can be opened and closed automatically, and the driving space is mechanically isolated from the passenger waiting space, creating a safe and comfortable waiting environment for passengers. Because there are many types of high-speed rail trains, and many factors such as different door layout positions of different types of trai...

AI Technical Summary

Problems solved by technology

However, in this technical solution, since the left / right sliding stroke is fixed, and each sliding door only realizes the door opening action through one-way movement, the adaptability of this method to vehicle models is actually limited, and it cannot be adjusted according to different models. Adjust the door opening position. For example, when the train door is just in the overlapping area of ​​the left / right sliding door, this solution cannot realize the alignment door opening
